Filter by:The objective of this study is to determine the prognostic performance of endothelial function assessment, using endothelial peripheral arterial tonometry (Endo-PAT), associated to TIMI risk score, in patients consulting the emergency department for non-traumatic chest pain. To determine the sensitivity, specificity, negative and positive predictive value of this method that was not previously used for this purpose.
Current evaluation of patients suspected of non-ST-elevation acute coronary syndrome is greatly dictated by the results of high-sensitivity troponins. In a substantial number of patients this approach does not provide a conclusive work-up. Patients typically present with slightly elevated high-sensitivity troponins without significant changes during serial sampling and no other clinical clues that can aid in determining the etiology of their chest pain complaints. Uncertainty remains about the optimal diagnostic management of these patients and they are often admitted to undergo invasive angiography. Coronary CT angiography can improve efficiency of clinical care in these patients by reducing unnecessary hospital admissions and invasive angiography. In this study, the investigators will investigate whether a diagnostic strategy comprising of early coronary CT angiography is more clinically efficient than standard optimal care in patients with an inconclusive work-up for non-ST-elevation acute coronary syndrome.
The post-thoracotomy pain (PTP) has been defined as persistent or recurrent pain that lasts for at least 2 month after thoracotomy and is associated with surgical incision or its intercostal nerve cutaneous distribution. The latter has a prevalence of about 15% to 20%. In about 80% of the patients such pain is moderate to severe in intensity and is associated with depression and insomnia. According to its characteristics and possible etiology, PTP is part of the neuropathic pain syndromes. Patients describe their chest wall pain as shooting, burning and numbness which are descriptors often seen in other neuropathic pain syndromes. PTP occurs most likely after partial or complete intercostal nerve damage secondary mechanical trauma (nerve traction or compression) during surgery. The concern is that when robotic surgery for minimally invasive approach to the heart valves or vessels such compression and consequent damage may happen to intercostal nerves. Therapeutic use for a lidocaine patch include post-herpetic neuralgia postthoracotomy pain, stump neuroma pain, intercostal neuralgia, diabetic polyneuropathy, meralgia paresthetica, complex regional pain syndrome, radiculopathy, postmastectomy pain and some other focal peripheral neuropathic pain syndromes. It is an effective and safe topical treatment. Its efficacy demonstrated previously in treatment of intercostal neuralgia and some patients with post-thoracotomy syndrome can be used in treatment of perioperative chest pain related to robotic cardiac surgery. Hypothesis is that the use of topical lidocaine will decrease pain in acute phase after the surgery and decrease intensity of post-thoracotomy pain 6 months after such procedure. The effect of topical 5% lidocaine will be clinically evaluated through prospective, randomized, placebo, double-blind study. Each patient will be assessed at admission and then, one week after Valve Replacement (Recommended surgical procedures do not included harvesting of leg vessels as this could be a potential confounder). Then, one month, three and six month follow-up for all patients by mailing questionnaires and phone calls. Upon admission, as well as 1 week, 1month, 3months and 6 months following surgical procedure, the following tests will be performed: - Pain Disability Index (PDI) - DASS - VAS Pain Score - Opioid use (in MSO4 mg equivalents) - Global Perceived Effect (GPE) or patient satisfaction
Rationale: This study aims to aid the general practitioner (GP) in the diagnostic dilemma of chest pain patients. Patients with acute coronary syndrome (ACS) should be referred to the hospital promptly, though referring all patients with chest pain is not feasible, as up to 80% of the patients with chest pain in the primary care do not have ACS. Objective: The primary objective is to refer patients who contact the out-of-hours GP cooperation (GPC) with suspicion of ACS more accurately with a hypothesized reduction of 10% in unnecessary referrals. Study design: This study is a prospective, observational, prevalence-based cohort study within the standard care of ACS patients. Study population: All patients with chest pain, or other complaints suspect of ACS, will be included in which the GP at the GPC is in need of further diagnostics to come to a decision of referral. The follow-up will be a registry of all patients with suspected ACS referred to the emergency department (ED). Patients with typical complaints of ACS, and thus a high suspicion, will be excluded and referred promptly. Intervention: Triage nurses working at the GPC will receive specific ACS training. Patients who arrive at the GPC with non-typical chest pain, will be screened for enrolment within the study. The GP evaluates patients using the Heart score, this includes electrocardiogram recording and point of care (POC) troponin testing. With the Heart score the GP can make an informed decision to refer the patient to the ED. To evaluate the intervention a registry of all patients referred to the ED with suspected ACS will be compared to a baseline registry performed from the 1st of September 2015 until the 1st of March 2016. Patients not referred to the ED, will have a (standard) high-sensitivity troponin and a POC troponin as follow-up at least four hours (up to 24 hours) after first measurement. The burden and risks associated with participation, benefit and group relatedness: Patients enrolled within this study will receive a finger stick blood test and electrocardiogram recording at the GPC and a finger stick blood test and a venous blood test at least four hours after first troponin measurement. We may follow-up by telephone if we can not obtain the required information from medical records. We expect no adverse events and there are no expected risks associated with this protocol. We expect patients with ACS to be referred more accurately and more promptly to the ED and thus lowering risks.
The aim of this observational study registry is to assess the safety of a Non-ST-elevation myocardial infarction (STEMI) rapid rule-out strategy as proposed by European Guidelines in patients presenting with suspected acute coronary syndrome to the emergency department.
This study aims to test an easily implementable web-based cognitive behaviour therapy (CBT) self-help intervention designed for non-cardiac chest pain patients, and compare effectiveness and cost-effectiveness to treatment as usual in an randomized controlled trial (RCT).
Multicentric, prospective, non-interventional observational study with two parts: 1. A register of quality assurance within the recertification of clinics 2. An extended register with scientific protocol.
This was a prospective randomized, controlled trial designed to quantify the reduction in cost and length of stay of early discharge of emergency department patients evaluated for acute myocardial infarction, who are deemed to be low risk based on a modified HEART score (a score that incorporates troponin biomarker, ecg, patient characteristics, and physician clinical judgment).
Coronary Computed Tomography Angiogram (CCTA) is a non-invasive imaging modality that has high sensitivity and negative predictive value for the detection of coronary artery disease (CAD). The main limitations of CCTA are its poor specificity and positive predictive value, as well as its inherent lack of physiologically relevant data on hemodynamic significance of coronary stenosis, a data that is provided either by non-invasive stress tests such as myocardial perfusion imaging (MPI) or invasively by measurement of the Fractional Flow Reserve (FFR). Recent advances in computational fluid dynamic techniques applied to standard CCTA are now emerging as powerful tools for virtual measurement of FFR from CCTA imaging (CT-FFR). These techniques correlate well with invasively measured FFR [1-4]. The primary purpose of this study is to evaluate the incremental benefit CT-FFR as compared to CCTA in triaging chest pain patients in outpatient settings who are found to have obstructive CAD upon CCTA (> 30% and < 90% stenosis). Invasive FFR and short term clinical outcomes (90 days) will be correlated with each diagnostic modality in order to evaluate positive and negative predictive value of each when used incrementally with CCTA. This will be an observational trial in which patients will undergo a CCTA, as part of routine care. If the patient consents to participate in the study and is found to have coronary stenosis of 30% to 90%, based on the cardiologist's reading, the CCTA study will be sent to HeartFlow, a vendor that will provide a computerized FFR reading, based on the CCTA study. If the noninvasive FFR diagnosis indicates obstructive disease, the patient will be recommended to undergo cardiac catheterization with invasive FFR. As CCTA utilization increases, the need to train additional imaging specialists will increase. This study will assess the capability of FFR-CT to enhance performance on both negative and positive predictive value for less experienced readers by providing feedback based on CT-FFR evaluation. CCTA readers will be grouped in two categories: those with more than 10 years reading experience and those with less than 10 years reading experience. Each CCTA will be read by a less experienced and a more experienced reader. Results from each reader will be correlated with each other and with the CT-FFR and invasive FFR results.
This is a prospective observational cohort study of ED patients with acute chest pain or other symptoms suggestive of ACS. Blood samples will be collected from study participants for High-Sensitivity Cardiac Troponin T (hs-cTnT) analysis. Results from hs-cTnT will be used for research purposes only. Providers will be blinded to results and participants will be treated by their healthcare providers per the standard of care. Participants will have 30 and 90 day phone follow-ups to ascertain study outcomes.
